The Frameset

As with tables, there are only three components absolutely necessary to build a framed page. Yes, frames can get a bit complicated, depending on the ways you want to employ them, but at the most basic level, all framed sites begin with the factors introduced here.

Any framed page requires a controlling XHTML document that gives the instructions on how the framed page is to be set up. This control is called the frameset. Then, an XHTML page is required for each individual frame.
